Abstract
Dans les appareils où sont logés plusieurs sous-ensembles, par exemple des plaquettes de circuits, ces sous-ensembles sont généralement enfonces dans des réglettes à ressort de connecteurs à emboîtement pour établir un contact avec les pistes conductrices dont ils sont munis. Ces réglettes à ressorts sont fixés à l'arrière du bâti de l'appareil. Pour enfoncer et extraire ces sous-ensembles, il faut déployer des forces considérables. Dans le dispositif selon l'invention, un levier 10 est monté à pivotement sur le sous-ensemble. A l'extrémité libre du petit bras de ce levier sont prévus des secteurs dentés 11 qui s'engrènent dans des tronçons de crémaillère 12 d'une règle profilée sensiblement horizontale et roulent sur ces tronçons lorsqu'on manoeuvre le levier. Pour immobiliser le levier dans la position où le sous-ensemble est enfoncé, il est prévu dans sa poignée 14 un élément de verrouillage 15 qui s'encliquète avec une saillie montée mobile dans un évidement du panneau frontal 7 du sous-ensemble 9. Le déverrouillage s'effectue en repoussant vers le haut un déclencheur 18.In devices where several sub-assemblies are housed, for example circuit boards, these sub-assemblies are generally driven into spring-loaded strips of interlocking connectors to establish contact with the conductive tracks with which they are provided. These spring strips are attached to the rear of the device frame. To drive in and extract these sub-assemblies, considerable forces must be deployed. In the device according to the invention, a lever 10 is pivotally mounted on the sub-assembly. At the free end of the small arm of this lever are provided toothed sectors 11 which mesh with sections of rack 12 of a substantially horizontal profiled rule and roll on these sections when the lever is operated. In order to immobilize the lever in the position where the sub-assembly is pressed, there is provided in its handle 14 a locking element 15 which engages with a projection movably mounted in a recess of the front panel 7 of the sub-assembly 9. The unlocking is effected by pushing up a trigger 18.
